Specification of Letters Patent.

Patented Aug. 14,1917.

Application filed January 22, 1917. Serial No. 143,880.

To all whom it may concern Be it known that I, REUBEN W. FINK, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Heating Device; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relates to heating devices, and particularly to a heating device adapted for use in connection with automobiles to maintain a circulation in the engine cooling system thereof and to heat the water in such system.

The object of my invention is the provision of a simple, efficient and inexpensive stove of the liquid fuel, preferably kerosene, burning type, which is adapted to be permanent y attached to an automobile under the engine hood and has a water heating coil in connection with the cooling water circulating system of the engine, whereby a heating of the water in the engine cooling system can be easily effected when the engine is at rest.

The invention is fully described in the following specification, vand while, in its broader aspect, it is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings, in which- Figure 1 is an elevation of an automobile engine equipped with my invention and with the water cooling means associated therewith, and Fig. 2 is an enlarged sectional view of a device embodying the invention.

Referring to the drawings, 1 designates an automobile engine of the internal combustion type, 2 the customary radiator of an automobile, and 3 the heating device embodying my invention, which is suitably mounted on the side of the engine crank case which is opposed to the side of the engine at which the carbureter is disposed.

The heating device 3 comprises a fount or tank 4 for containing the kerosene or other liquid fuel to be burned in the device, said tank having an opening in its top through which the wick 5 extends, the wall of said opening being formed by an upstanding annular flange 6. A tube 7 extends from the bottom of the tank 4 up through the flange 6 in spaced relation thereto and serves as a guide for the tubular wick 5, which is mounted for vertical movement thereon. The upper and .lower ends of this tube are open to permit an upward circulation of air therethrough. 8 designates a hand-wheel, which is operable to effect a raising or lowering of the wick.

A drum 9, in the present instance of cylindrical form, is provided at its lower end with a central opening having a marginal flange 10 of annular form projecting outwardly therefrom and adapted to telescopically fit over the flange 6 of the tank 4, thus positioning the upper end of the wick 5 within the lower end portion of the drum 9 when the drum is in position over the tank. An annular casing 11 rises for a short distance in cylindrical form from the bottom of the drum 9. interiorly thereof in concentric outwardly spaced relation to the bottom opening through which the wick projects and has its upper end portion flaring outward in the form of a cone frustum and terminating adjacent to the upper closed end of the drum. This casing forms a combustion chamber within the drum, the products of combustion finding an exit" therefrom over its top edge and thence from the upper end portion of the drum through a series of small exit openings 12 provided in the upper end portion of its side wall. A deflector 18 of frusto-conical form extends downward from the upper end of the drum into the casing 11 to adjacent the lower end thereof and is in spaced concentric relation thereto to provide an annular conical passage between the casing 11 and deflector 13. This deflector has a closed bottom. A plurality of small openings 14 are provided in the lower end of the drum between the flange 10 and casing 11 to permit air to enter the lower end of the combustion chamber around the wick to facilitate combustion.

A water circulating coil 15 encircles the deflector 13 in the path of the flame and heated products-of combustion which pass upward through the space between the casing 11 and deflector 13 when the burner is in operation, thus highly heating the coil and effecting a circulation of the water therein. The ends of the coil 15 are connected to different portions of the water circulating system of the engine so that the circulation set up Within the coil will be connnunicated to the major portion of the cooling system of the engine. In the pres ent instance the cooling system is shown as provided with a circulating pump 16 and the ends of the coil are connected to the water. circulating line at opposite sides of this pump.

It is evident that my improved heating means may be left permanently attached to the en ine during the cold months of the year and removed during the warmer months when the heating means is not required. It is also evident that the drum 9 may be disconnected from the tank -l for the purpose of trimming the wick or clean ing the interior of the drum. It is not necessary, however, to remove the drum when lighting the wick, as a door or match-introducing opening may be provided in convenient position for such purpose.

I wish it understood that my invention is not limited to any specific construction, arrangement or form of the parts, except in so far as such limitations are specified in the claims.

- Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A heating device of the class described, comprising a liquid fuel tank having an opening in its top for receiving a wick, a

drum removably mounted on said tank, and

having an opening provided centrally in its bottom in register with the tank opening, a casing rising cylindrically a short distance above the bottom of said drum interiorly thereof in surrounding spaced relation to said bottom opening and then flaring upward in the form of a cone frustum and terminating at its upper end adjacent to the top of the drum, a hollow frusto-conical deflector projecting down into said casing in spaced relation thereto from the top of said drum and terminating at its lower end adjacent to the bottom opening. in said drum, said deflector having its large upper end open to the atmosphere through the top of said drumand having its lower small end closed, and a liquid heating coil dis posed in the space between said casing and deflector in spaced relation to both, said drum having exit openings at its upper portion.

2. A heating device of the class described comprising a tank having an opening in its top and an annular flange rising from the tank in surrounding relation to said opening, a tube extending up through the tank and into said flange, said tube being open at its top and bottom, a drum having a centrally disposed opening in its bottom and a flange extending from said opening for telescopically fitting over said tank flange, a casing rising from the bottom of said drum interiorly thereof in surrounding relation to its opening and having its upper portion outwardly flared and terminating short of the drum top, said drum havingiexit openings in its Wall, a wick mounted on the tube in said tank and extending from the interior of the tank into the lower end of said drum casing, a conical deflector projecting from the top of the drum down into said casing in spaced relation thereto, and a coil encircling said deflector within said casing and having its ends projecting without the casing.

In testimony whereof, I have hereunto signed my name to this specification.
